<details>
  <summary>Usage</summary>

```sh
# print the command to be executed and immediately start it
echo 1 2 3 4 | xargs -t mkdir

# print the command to be executed and ask for confirmation before starting it
echo 1 2 3 4 | xargs -p rm -rf

# spawn 5 clamscan processes at a time
# each process being given 1 argument from the list in input
find ~ -type f -printf "'%p' " | xargs -P 5 -n 1 clamscan

# replace a given string with arguments read from input
# useful to insert the arguments in the middle of the command to execute
find ~ -type d -name ".git" -exec dirname {} + | xargs -I // git -C "//" pull

# Use aliases as commands.
# The 'BASH_ALIASES' array works only in BASH.
# The 'aliases' array works only in ZSH.
echo 1 2 3 4 | xargs "${BASH_ALIASES[my-alias]}"
echo 1 2 3 4 | xargs $aliases['my-alias']

# Execute interactive commands.
# Reopen the TTY with '-o', '--open-tty'.
grep -lz PATTERN * | xargs -0o vi
find '.' -type 'f' -name 'Pulumi.yaml' -not -path "*/node_modules/*" -exec dirname {} '+' | xargs -otI%% pulumi up -C %%
